Shareholders exercise their rights at the General Meeting and vote there. In principle, each share carries one vote. There are no shares with multiple voting rights, preferential voting rights (golden shares) or maximum voting rights. The Management Board submits to the General Meeting the Annual Financial Statements and the Consolidated Financial Statements. The General Meeting resolves on the appropriation of net income and the discharge of the acts of the Management Board and of the Supervisory Board. It elects the shareholders' representatives to the Supervisory Board and, as a rule, the auditors. Furthermore, the General Meeting resolves on the Articles of Association, the purpose of the company, amendments to the Articles of Association and essential corporate measures such as, in particular, inter-company agreements and transformations, the issuing of new shares and, in particular, of convertible bonds and bonds with warrants, and the authorization to purchase own shares. When new shares are issued, shareholders, in principle, have pre-emptive rights corresponding to their share of the equity capital. Each shareholder is entitled to participate in the General Meeting, to take the floor on matters on the agenda and to submit materially relevant questions and proposals. The chair of the meeting provides for the expedient running of the General Meeting. At least once a year the shareholders' General Meeting is to be convened by the Management Board giving details of the agenda. A quorum of shareholders is entitled to demand the convening of a General Meeting and the extension of the agenda.
